METAL PACKING.

Application filed. February 13, 1921.

To all whom it may concern:

Be it known that I, PAUL R. ENDELL, a citizen of the United States,residing at Chica o, in the county of Cook and State of Illinois, haveinvented new and useful Improvements in Metal Packing, of which thefollowing is a specification.

This invention relates to metal packing for use in stuffing boxes andvarious types of machinery, and an object of the invention is to providea yieldable, noncompressible metal packing which will yield, undercompression, to securely pack or seal a joint, but which will not becomehardened or compressed under successive applications of power orpressure there against.

Another object of this invention is to provide a yieldable,noncompressible packing which will readily lend itself to shaping forproviding the most practical and desired shape of packing depending uponthe use to which it is to be put.

A further object of this invention is to provide a metal packing whichwill require only a simple process in the forming and shaping thereof.

Another object of this invention is to provide a metal packing which isformed of sheets of pliable metal having one surface covered or coatedwith a liquid after which the pliable sheets of metal are crimped orcrushed to provide irregular shapes to the metal in cross section andalso provide pockets of irregular shape within the body of the packingformed by the crushing of the sheet metal to prevent compressing of thepacking.

Other objects of the invention will appear in the following detaileddescription and in the accompanying drawing wherein:

Fig. 1 is a perspective view of one form or shape of the packing.

Fig. 2 is an edge elevation of a sheet of pliable metal showing itcoated with liquid prior to the crushing of the metal and illustratingthe first step in the process or method of forming the packing.

Fig. 3 is an edege elevation of the pliable sheet metal partiallycrushed into packing shape and illustrating the second step in themethod of forming the metal packing.

Serial No. 444,455,

Fig. 4c is a section through a modified form of the packing.

Referring more particularly to the drawing, it is to be understood thatwhile the piece of the metal packing shown in Fig. l of the drawing isrectangular in shape, that the improved packing may be made in anyshape, such as cylindrical, polygonal in cross section, or any shapedesired, depending upon the place it is to be used and the work to beperformed by it.

In forming the metal packing a sheet 1 of pliable metal, such as sheetBabbitt metal or the like, is first coated with a liquid such ascylinder or lubricating oil as shown at 2 in Fig. 2 of the drawing,after which the sheet of pliable metal is bunched or crushed, asillustrated in Fig. 2 of the drawing to provide irregular shapes to thesheet and to provide a regular outer surface to the composite piece ofpacking formed by the crush ing of the sheet, the outer shape dependingupon the use to which the packing is to be put. The crushing of thesheet of pliable metal from two opposite edges will provide, besidesirregularities in the shape of the metal, irregular pockets within theformed packing in which the liquid 2 will be con-- fined providing ayieldable, noncompressi ble packing. Any suitable type of liquid may beemployed without departing from the spirit of this invention. If it isso desired the formed piece of packing may be encased in a suitableshell as illustrated at 3 formed of asheet of pliable metal, PI'GfQlEably of the same type as the sheet 1.

The formation of the irregularly shaped pockets in the packing, whichpockets will have their ends closed and will not extend throughout theentire length of the packing will prevent the liquid from oozing out ofthe ends of the packing, however, in forming a continuous piece ofpacking it may be desirable to provide pockets therein which arecomparatively regular and extend throughout the length of the continuouspiece of packing and such a modified form is illustrated in Fig. 4 ofthe drawing.

It is, of course, to be understood that the invention may be constructedin various other manners and the parts associated in different relationsand, therefore, I do not ets, a lubricant in said pockets and an outerdesire to be limited in any manner except as casing of pliable sheetmetal of the same 10 set forth in the claim hereunto appended. type asthe core and folded about the Having thus described my invention whatcrushed pliable sheet metal core to entirely 5 I claim is: enclose thesame.
